Abstract (en)

[origin: EP4218831A1] The present invention is a method for evaporatively concentrating a radioactive metal nuclide, including: a first evaporative concentration process in which a radioactive solution formed by dissolving a radioactive metal nuclide in an acidic aqueous solution is heated to evaporate a solvent in the radioactive solution so as to obtain a concentrated liquid containing the radioactive metal nuclide; and a second evaporative concentration process in which a low-boiling organic solvent having a lower boiling point than water is added to the concentrated liquid, and the concentrated liquid is heated to induce azeotropic boiling of the concentrated liquid and the low-boiling organic solvent so as to obtain an evaporative concentrate of the radioactive metal nuclide. According to the present invention, it is possible to perform, without manual intervention, the processing from the separation of a radioactive metal nuclide from a radioactive solution formed by dissolving the radioactive metal nuclide in an acidic aqueous solution, to the production of a radioactive labeled substance by causing the radioactive metal nuclide to react with a label-target compound.
